SPRAY-NOZZLE.

Specification of Letters Patent.

Application filed February 7. 1906. Berialo. 299.944-

To all 'whom it may concern:

Be it known that I, WILLIAM H. HEARD,

of spray nozzles to the end of a fluid conduit4 bent at an obtuse angleto the main part of the conduit, the spray nozzles being directedforwardly,'but at an angle to the Inain part.

of the conduit, substantially as hereinafter more s ecically describedand then definitely. c aimed.

Figure 1 is a side elevation showing a nozzle cluster, with the spraydirected upwardly. Fig. 2 is a similar view showing the lance turnedthrough 18Q and the spray directed laterally. Fig. 3 is an enlargedperspective view of the nozzle cluster. Fig. 4 is a verti- .calsectional elevation on a still larger scale,

of a single nozzle. Fig. 5 is a erspective v1ew on the same scale, of anozz e with the the drawings like letters of reference indicatecorresponding parts in the different lfigures.

' In 1ts fundamental form my invention comprises a iiuid conduit whichmay comprise a pipe A and a chamber C connected thereto at an obtuseangle at the'point a, one or more spray nozzles B being connected withthe chamber forming the end of the conduit, and'adapted to discharge, ina forward direction, but at an angle to the main part of the conduit.

It is preferable that the spray nozzles be arranged to deliver theirspray in a direction substantially at right angles to the forwardsurface of the end of the conduit, except for the fact that to spreadthe spray to the best advantage when a plurality of 'nozzles areemployed, the nozzles are slightly inclined away from one another,producing a spray cloud of greater diameter than if the nozzles wereparallel to one another;

In practice I 'find it preferable to have the chamber forming the endofthe conduit at an angle of 135 to the main part of the conduit, aswith this angle I nd the most eective work can be done. For instance,supposing one side of the exposed surface of a tree is to be. sprayed,the operator may, without changing the inclination of the part o f theconduit he holds in his hands, discharge the spray upwardly against theunder side of the surface-of the tree, laterally against either side, ordirectly against the nearest part of its surface, while with the partsin the posi-r tionshown in Fig. 2, the spray is easily dropped onto thetop of the tree. Thus an operator, without changing his position, with acomparatively small movement of the conduit, may spray one-half thesurface of a large tree, and with high pressure, and the employment ofnumerousv nozzles in the cluster, moderate sized trees may be completelys rayed on one side while the apparatus is eing drawn past them'.

The arrangement of the apparatus I prefer is substantially that shown inthe drawings, the bent'end of the conduit being formed by the chamber C,preferabl annular inshape, and provided with a soc et D at an obtuseangle thereto, preferably 135.. This socket is connected with the pipeA, which is preferably the ordinary extension rod or lance em- -ployedwith spray nozzles, and which is provided with a drip cap E.

The upper surface of the chamber C is preferably shaped as a frustumofla cone, and a series of spray nozzles are set equidistant from oneanother around the chamber, each having its aXis normal to the surfacefrom i which it extends. Owing to the outward inclination thus given toeach spray nozzle, the united spray is given as large a diameter as ispossible, and of even quality throughout, as the separate spray fromeach nozzle interferes as little as possible with the spray fromitsneighbors.

F is the supply pipe of the nozzle, its lower end being screw threaded,for connection with the chamber C, as shown in Figs. 1, 2 and 3. Thissupply pipe4 has a closed, enlarged end G formed thereon. Inclosing theend of the pipe is a casing formed in two arts, H and screwed together.The ower part H has a shoulder or collar J formed thereon, adapted tofit beneath the shoulder formed b the enlarged end G. Between they twols oulders, a washer K is placed. The upper part I has 4a centralopening therein, round w'hich is formed a shoulder L, between which andthe upper end of thelower part H of the casing is placed adisk M, and awasher N. In the center of the disk M is formed a spray opening b.Through the end G is formed a hole 0, communicatin with the inner boreof the supply pipe F. n the sides of the end communicating with the endsof the hole O arey formed helical grooves P extending out through thetop of the enlarged end. The extreme end of the part G is preferablreduced in diameter. On the center o the end Gr is formed or secured thedisgorging needle Q.

From the construction described, ift follows that the nozzle may bedisgorged ,at any time by merely pressing its end against any resistingobject, the pressure of the fluid within 1t immediately restoring thecasing to its normal position. i

What I claim as my invention is: Y

1. In spraying apparatusa fluid conduit bent at an obtuse angle near itsdischarge end, and a plurality of spray nozzles connected with sail endand adapted to clischarlge at var in an esa proximat' ta es to theyaxs othe ent end biilarllg in ansgubstantially forward direction and atanvangle to lthe main part of the conduit, substantial.y as described. Y

2 In spraying apparatus a fluid conduit comprising a pipe and a chamberconnected at one side with the-end. of said'pipe and at an obtuse anglethereto, and a plurality of spray nozzles yconnected with the chamber atdifferent parts of its forward surface and adapted to discharge in asubstantially forward direction but at an angle to the conduit,substantially as described.

3. Inspraying apparatus a fluid conduit comprising a pipe and an annularchamber .adapted to dischar e at varying connected at one side withtheend of said pipe and at an obtuse angle thereto, and a plurality ofspra nozzles connected with the chamber at di erent parts of its forwardsurface and adapted to discharge in a substantially forward directionbut at an angle to the conduit, substantially as described.

4. Inspraying apparatus a fluid conduit comprising a pipe and an annularchamber connected at one side with the end .of said pipe and at anobtuse angle thereto, and a plurality of spray nozzles connected withthe chamber at different parts of its forward surface and'adapted todischarge at varyin angles but all in a substantially forwar directionand at an angle to the mainpart 5.* In spraying apparatus a fluidconduit comprising a pipe and an annular chamber connected at one sidewith the end of said pipe and at an obtuse angle thereto, and aplurality of spray nozzles connected with the chamber at different partsof its surface and angles but all in a substantial y forward directionand at an angle to the main part of the conduit, each spray nozzlecomprising a part connected with the end and carryin a disgorging needleand a cap longitudina y,movab e on the said part and provided with aspray aperture opposite the disgorg'ing needle, sub1 stantially as.described London, Ont.
